My invention refers to a multiple twinecan or holderfor the twine usedfor the automatic binding of the sheaves in selfbinding harvesters, the type of the harvest- Sing machine itself and thebinding' apparatus used in connection therewith being independent of the invention." L

In the types oftwine-holders hitherto in use for the aforesaid pu'rpos'e,'two balls of 0 twine have been placed one upon the other in a common can, the deliveryof the twine commencingfrom the interior of the upper most ball. The outer end of the upper ball has been connected with the inner end of 5 the lower one, and after the upper ball has been consumed, the delivery takes place from the lower one in the same manner. Finally, when there remains a thin shell of the lower ball only, the can must be refilled,

and this is. performed by lifting the highly reduced lower ball out of the can, connecting-the. outer end thereof with the inner end of a fresh ball and placing the-latter on the bottom of the can, the partly used ball being again inserted on top of the fresh ball.

It is-evident that this handling of a ball, which is substantially consumed, is very delicate, and frequently it results in that the wise deformed so that the twine gets entangled'and is either delivered in the'form of an entangled knot or torn mi, and most 1y this mishap escapes the notice of the attendant of the harvester until a plurality of unbound sheaves have been fed out from the same. Besides, in twine-cans; of this kind,'it is not possible to use balls which completely fill the can in transverse direction, but the balls must bea little" smaller than the latter. Then, they will get no steady seat in the can, and when being thrown about therein during the travel of the machine on a frequently very uneven ground they are still further liable to be deformed and to form entangled knots.

According to the invention, all of these inconveniences are eliminated, and generally the invention is based on the. principle of using a plurality of separate cans each two separate ball cans, only,

ASSIGNOR To svEivsKA Bruno-Anus adapted for holding Olle singleball, whereby theinner end ofone ball is connected with the outer endof anotherone. Based on this general principle, the construction of athe can may'naturally vary in many ways in practice. 'Although for all practical purposes it may be found sufiicient'to employ may naturally 'be provided with. a"? greater number thereof, in case the space available in the harvester is suflicient therefor-e.- In several instances'it may be favorable 'to"employmoreithan two c'ans, as i't1is"evident* that the greater quantity of twine that can becarried by the machine at the' same time, the less frequently it must be stopped for refilling the cans. .Further, it issuitable'to the apparatus place all of the'canssubsantially at the same level in themachine, i. e.- side by side, but

nothing prevents another positioning-of the same, for instance in a pile above each other,

the main point being that separate cansare used for eachball, so that no .lifting'out of partially consumed b'a'lls is required ror 7 the refilling. Hereby it willalso be possible to use solarge balls thatfthey completely fill out, and even fit tightly within, the cans, and each ballwill thereby be may also be secured by means of small pins adapted to stick into the bottom end :of the balls, such pins being mainly adapted to prevent a rotation of the ballsduring the delivery of the twine.

7 given a steady seat in its can; Furthermore the steady seat said shell of a ball is pressed fiat andother paratus must be refilled, and this step isgeffected simply by insertion offresh balls-in the empty can or calls, whereafter the ends" of the balls are connected as stated above and the inner end of the first of .themzwith the outer end of the remaining ball rest, the said} outer end of which has previously been positioned'inreadines's for suchpurpose.

Theguiding of the twine outside of the cans may also be. effected in. different ways,

V and the means used heretofore will mainly be dependentfor their construction of the number of cans employed. A. .pair of parallel '10- v v panyingdrawin'g,

bars springactuated in a direction towards each other and serving also as a tensioning means -for-thetwine and extending along the c po'olsh. The: volume of the cans shall be the greatest possible'in' order that the apparatus Qra't'the edges opposite zto the hinges, such rod "open in upward movable lids '6 to the embodiment shown shall a -have thet greatest possible holding In "the x'einbodiment shown, the are direction and closed by reand 7 respectively, suchlids zat= their xi. oer-facing :sides' being provided with radial slots 8 and respectively extendf substantially from the centre and entire- =rliy =to-the very edge of each lid. *The lids 6 and 7 :are' mounted-on hinges 10 :and'll and kaft th'e edges of-theilids facing the hinges, the

*lids-ereinterconnected by means ofa rod 12' 'carry1ng-;af:gu1de :eye 13' for the twine positinned-between the cans. T-helockin'g of the lidslin-a closed position can naturallybe perbut accordthe locking means consist of a rod-14 connecting the lids f r d in many different ways,

.'fl beingrprovidedwith a slot for coaction "with ascrew-15 h-in gedly connected with the fifor scnews 20, 21 extending member ;3 and naitor theilike'. Approximately .at their centres the lids are al'so'in'terconnecte'd by means of'a bar 16 positioned parallel to i s il'o'osely. laced upon the former. At its ends thebar 1 I is provided with free holes from the lids and provided with wingnut-s 1'8, 19, a coil spring and 23 respectively being positioned -arounde'aohof the said screws between the huts thereon and thej'ends ofthe upperbar 17 ,-so that'the bars 16 and 17 are pressed ztowards each-other with a force correspondingto .the tight'ening of the wing nuts 20, 21,

. I such force or pressure being-apparently variablezat will. i

AsWi ll beseen from the drawing, the flat bars 16' and'17 are not truly parallel, but seen in transverse direction they forni a small i-q lii-glo ivith itch other the .gap of such angl referencesil and 2 repball, ,for instance in.

edwith the outer end ofrtheballinjthe tioned can.

111 the can 2 1s carrled between the tensiomng provided with-a winged the slots "8, 9, and another being directed towards the side from which the twine is to be entered between them.

7 At that side, the tensioning guide eye 13, the edges of the bars ought to be rounded ofiiso as not to have any tearing orscraping action on' the twine, and the angular inte'r-relation of bars referred to above is intended for facilitating the entrance of "eventual knots on the, twine between them.

' 'One of thecans, for instance the can 5,is

exterio'rly provided with a spring clip or the like 24 adapted for 'aflixingone end offthe twine, and interiorly thebotto ns of the cans may be provided with upstanding pins or spikes (not shown) extendingiinto theballs from beneath andpreventing-their rotation withinthe'cans.

at whichthe twine leaving 7 bars shall go through the WVhen the twine-h0lder to be ,use chaball ballsbeing of asize suflicient for completely filling up the cans. The outer end of one throughthe slot in the lid-on the same and affiXedto' the cIipQL, the inner end of'the.

knot being connect other cup '2, the latter twine-end being drawn Pout through the. slot in" the lid" on the last men- Finally the inner end of the ball same ball by meansofa bars 1'6, 17 and-outthrough the guide eye 13 to the binding apparatus of the harvester; In this" case, when the twine in the first ball,

i. e. the ball 5, has been totally consumed and the twine in the second ball 6. had also'been substantially'consumed, thelid 7 isopened,

and a fresh ball is'inserted in the can-2. The twine end affixedto the clip 24 is released and connected with the-inner end of the said fresh ball, the outer end of which in its turn being aflixed to'the clip 'Qfor use when in serting a freshball in the second can 1. 1:

. 'Here'from it will be-apparent that the delivery ofv the twine, will always take, place from the interior of the balls, and when. once inserted, it is not needed to handle anymore or less consumed ball, but the balls may be left entirely to themselves after insertion'and until they are completely consumed.silence, the balls maybe made to fit very closelyinto the cans, and the risk for V deformation 'of ,more or less consumed balls by changingtheir position whenrefilling the-holder is jentirely eliminated. -The' tensioning of thfltwine leaving the guide eye 13 may naturallybe varied by more or lesstightening of the wing nuts 18,19. The complete arrangement may easily be mounted and demounted on any self binding harvester now inuse. Having now described; my invention antc' ;the manner in: which it is to be per-forms I declare 'that'what'I claim is 1. In a twine-holder. for'self-binding han vesters, two separate twin-cans each adapter of twine is inserted in each of the cans such the can.1,'is drawn out p for the accommodation'of one single twine ball,.a lid on each can, a slot in each lid ex to be passed by the twine fed outthrough .the same.

2. A twine-holder for self-binding harvesters according to claim 1, in which the cans are mounted substantially at the same level, and being of substantially the same height, and provided with lids interconnected by means of. the twine tensioning and guiding means mounted on the lids.

'3. In a twine-holder for self-binding harvesters, two separate twine-cans each adapted for accommodation of one single twine ball, a lid on each can, a slot in each lid extending substantially from the center portion and entirely to the edge thereof, the open ends of the slots being positioned so as to face each other, a first bar member positioned along the slots in the lids, a second bar member loosely laid upon the former and shaped to form a small angle with the latter in transverse direction, spring means acting upon the bar members to press them together, and guide means for guiding the relative movement of the bar members in relation to each other.

4:. A twine-holder for self-binding harvesters according to claim 3, in which the first bar member is rigidly connected with the lids to interconnect the same, the guide means at the ends of the bar members consistin of screws extending-from the lids and provlded with nut means, and coil springs surrounding the said screws and interposed between said nut means and the second bar member.

In testimony whereof I have signed my name to this specification.
